ments in Fluid-Delivery and Pressure-Gov erning Devices, of which the following is a full, clear, and exact description.

This invention has for its object to provide an improved form of bubbler for drinking fountains, "wherein the water is caused to pass through a tortuous passage with obstructionstherein to reduce the pressure, and in which the meansforming the obstruction is automatically regulated by the pressure of the water, forming a govout at the outlet opening in a steady and even stream.

In the accompanying drawing showing one embodiment of my invention v a Figure l is a vertical axial section through the'device; Fig. 2 is a sectional-view of the bubble sleeve member. Fig. 3 Shows the valve device detached, and Fig. 4 is a perspective view of the device.

' being shown as fitted in an enlarged por-' The device is shown as comprising a body member 6 having a bore 7 extending down from, the top, which has an outlet 8 in thebottom thereof. A .sleeve member 9 is secured at the upper part of the body member,

" 'tion 10 of the body and secured therein by v the side walls and bottom thereof. The err--v a suitable means such as by soldering; which sleeve is provided with a reduced extension? 11 having the lower end 12 closed, and pro-i jecting down intothe bore 7 but oifset from tension 11 is provided with openings 13 at the upper portion leading into the "bore 7 and perm' ting the water which will pass up through the inlet 8 and between the sleeve extension and the bore, to enter the interior of the sleeve. It will be seen that the sleeve- 9' projects upward some distance above the casing 6, and in the lower part of the sleeve slides a-valve 14 provided with a stem 15 extending downward and connecting with a head portion 16 which slides in the sleeveextension 11 below the opening 13 therein; The

sleeve 9 at its lower portion where secured to the casing is provided with lateral openings 1'7 registering with openings 18 in the portion it 'wil casing; which will permit thewater enter- 4 TED STATES PATENT OFFIC stem 15 and then outwardly below the valve 14, and through these registering openings 17 and 18; when the valve head 16 is in its lowermost'positicn as shown, but should the valve rise the head 16 will throttle the opening 13 and'restrict the flow of the water upward. But the water flowing upward and i engaging the lower face 14' of the valve will tend to move the valve member upwardly; andthis tendency will be the stronger as the pressure of the water increases; therefore, suitable opposing means for the valve must be provided, and a coil spring 19 is shown engaging the top of the valve, and a casing 20 is shown adjustably secured on'the body at the threaded portion 21 thereof, whereby and vary the tension on the spring, Whose upper end enga es the top 22 of the casing. It will be seen t at the casing is ofiset some d stance from the Sleeve member 9 at the side and at the top, and the'casing has an outlet openin 23 at the top from which portlon adepen ing annular extension 24 proects downwardly inside .of the said sleeve 9, and oflset a short distance therefrom to perm1t free movement of the spring between these sleeves.

of the openings 18 in the top of the body the casing and the sleeve 9 to the upper part of the casing; thereupon the water must pass downbetween the sleeve 9 and the de-;

pending annular extension 24 and around or through the spring, in order to reach the opening at the inner lower end of the said the casing can be turned to raise or lower it 7 It will be seen that as the water fl'ows out.

w 1 pass upwardly between the bodyandthe casing, and thence between;

annular extension. Thisof itself will form an obstruction to reduce the force and flow of the water, which will emerge at the top ofthe passage 23 in a Slow and steady stream. further restricting means are provided which can be adjusted to varying pressures of thewater, the casing being providedwith an "internal flange 26 having its lower face inclinedandthe upper edge. of

the body member is similarly inclined, and as thewater-mnst flow-between these inclined' faces'up through-the casing, it will be understood that-screwing the casing up 0':- I

" down will vary thedistance between these passage of the water. In order to prevent inclined, faces and more or less throttle the a resistance at the i bfbottom' of the valve head 16, the head and stem are provided with a small bore 28 lead- 4, "ing upward from the lower end and having a lateral opening 29' at one or more sides through the stem, permitting the water to flo flow in. and down this bore to pass below the head as. the valve moves upward; but this will not interfere with the action of the i water o'n'the face 14' of the valve 14.

In the operation of the device, the water i I: I flows up through the inlet 8 and around the 'lsleeve extension 11, through the openings therein around the valve stem to pres onthelower face of the valve 14; and thence I the water passes out the lateral openings 17 201and 18, and then up between the inclinedfaces 26,"and upwardly between the casing endv 23, thence down around the coil spring to the lower end of the ,outletopening 24 r and'fthen out through the same. The waterv y '25 will tend to' force the valve upwardly and "compress the spring until these pressures- "c'ounterbala-nce, and the proper adjustment of the spring is accomplished by turning the; casing 20';-so that only an abnormal pres- 30sure will elevate the valve and restrict the opening 13 and reduce the flowof the water It will be seen that the adjustment of the -'spring can be done at any time without tak-- ing the device apart or employing any tools,

ii-it being only necessary to turn the casing 20.

While the invention is shown applied to a bubbler for drinking fountains, it is manifestthat it can be used as a means for regulating the pressure 'or 'fiow of the water 4 for any purpose, and an outlet conduit can i 'head as it moves upwardly, and form a- "strong 'resistance .to the subsequent downward movement'of the head, and thereby "interfere with the proper operation of the device. But by having these openings such 'accumulationofwater can find exit through "these passages.
